Internet issue in SC20 using EC25 via qmi interface

I am using EC25 on SC20 evk board via qmi interface in Android 7. GSM is working fine but internet service is not working. It is showing cross mark (x) on network signal icon as shown in the pictures. I am using RIL layer shared by quectel of version 3.2. I am attaching the log file too.
Please go through the below drive link to find the files.

Could you show me the modification you have done in source code.
Are there any quectel’s FAE support you with this work?
